refactor: replace meta/ PKGBUILDs with plain text package lists

- Convert 16 PKGBUILD metapackages to simple .txt files (one package per line)
- Delete all PKGBUILD, .SRCINFO, and .pkg.tar.zst binary artifacts
- Clean stale packages: lf→yazi, tmux→zellij, neofetch→fastfetch, stow→chezmoi
- Remove duplicate rustup in dev, duplicate mesa in intel
- Add justfile recipes: install, install-all, status (unified drift detection)
- Configure chezmoi to exclude scripts from status/diff output
- Update copilot instructions
